I have a similar fantasy, but with a more 'hands on' approach. I am gagged, with my hands tied behind my back. The woman looks me up and down, making comments are made about me. Particular attention is paid to my penis.
I become erect; she grabs my cock and leads me around by it. She tugs, pulls and stretches. I am helpless to go wherever she leads. She digs her nails into my cock and balls and comments on my size. She doesn't let me climax and laughs at how easy it is to control me.
She invites a few friends over. I am embarrassed to be naked in front of so many women. They take turns leading me around and laugh that I have to go wherever they want. They comment that I am too small to be worthy of them and so I am only good enough to be led around.
It's strange - I'm not submissive at all except for this scenario. I can't get it out of my head.
